Cytisus plant named ‘SMNCSCRY’

ABSTRACT

A new and distinct cultivar of  Cytisus  plant named ‘SMNCSCRY’, characterized by its relatively compact and upright to outwardly spreading plant habit; vigorous growth habit; freely branching habit; full and dense plants; freely flowering habit; large bright yellow and red-colored flowers; and good garden performance.

Botanical designation: Cytisus scoparius.

Cultivar denomination: ‘SMNCSCRY’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Cytisusplant, botanically known as Cytisus scoparius, commonly referred to asScotch Broom and hereinafter referred to by the name ‘SMNCSCRY’.

The new Cytisus plant is a product of a planned breeding programconducted by the Inventor in Grand Haven, Mich. The objective of thebreeding program is to create new compact and uniform Cytisus plantswith attractive flower form and color.

The new Cytisus plant originated from an open-pollination in 2009 inGrand Haven, Mich. of an unnamed selection of Cytisus scoparius, notpatented, as the female, or seed, parent with an unknown selection ofCytisus scoparius as the male, or pollen, parent. The new Cytisus plantwas discovered and selected by the Inventor as a single flowering plantfrom within the progeny of the stated open-pollination in a controlledenvironment in Grand Haven, Mich. during the spring of 2013.

Asexual reproduction of the new Cytisus plant by softwood stem cuttingsin a controlled environment in Grand Haven, Mich. since the spring of2013 has shown that the unique features of this new Cytisus plant arestable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Cytisus have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘SMNCSCRY’. These characteristics incombination distinguish ‘SMNCSCRY’ as a new and distinct Cytisus plant:

-   -   1. Relatively compact and upright to outwardly spreading plant        habit.    -   2. Vigorous growth habit.    -   3. Freely branching habit; full and dense plants.    -   4. Freely flowering habit.    -   5. Large bright yellow and red-colored flowers.    -   6. Good garden performance.

Plants of the new Cytisus can be compared to plants of the female parentselection. Plants of the new Cytisus differ primarily from plants of thefemale parent selection in the following characteristics:

-   -   1. Plants of the new Cytisus are denser than plants of the        female parent selection.    -   2. Plants of the new Cytisus are more freely flowering than        plants of the female parent selection.    -   3. Plants of the new Cytisus have larger flowers than plants of        the female parent selection.    -   4. Plants of the new Cytisus and the female parent selection        differ in flower color as plants of the female parent selection        have yellow-colored flowers.

Plants of the new Cytisus can be compared to plants of Cytisus scoparius‘Madame Butterfly’, not patented. In side-by-side comparisons, plants ofthe new Cytisus differ from plants of ‘Madame Butterfly’ in thefollowing characteristics:

-   -   1. Plants of the new Cytisus are more compact and upright than        and not as outwardly spreading as plants of ‘Madame Butterfly’.    -   2. Plants of the new Cytisus and ‘Madame Butterfly’ differ in        flower color as flowers of plants of ‘Madame Butterfly’ are        lighter yellow in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearanceof the new Cytisus plant showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotographs may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Cytisus plant.

The photograph on the first sheet comprises a side perspective view of atypical flowering plant of ‘SMNCSCRY’ grown in a container.

The photograph on the second sheet is a close-up view of a typicalflowering plant of ‘SMNCSCRY’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations andmeasurements describe plants grown in three-gallon containers during thespring and summer in a polyethylene-covered greenhouse in Grand Haven,Mich. and under cultural practices typical of commercial Cytisusproduction. Plants were two years old when the photographs anddescription were taken. During the production of the plants, daytemperatures ranged from 18° C. to 27° C. and night temperatures rangedfrom 5° C. to 10° C. In the following description, color references aremade to The Royal Horticultural Society Colour Chart, 2015 Edition,except where general terms of ordinary dictionary significance are used.
